Product Details

Dayton Audio PT2C-8 Planar Tweeter

Many audiophiles praise the Dayton Audio PT2C-8 ribbon tweeter's excellent clarity, transparency, and imaging. The key to this remarkable performance is the almost weightless ribbon element: a Kapton film membrane etched with a pattern of aluminum conductors and placed precisely between two rows of neodymium magnets. The result is an immediate response to any transient impulse found in the original signal.

The Dayton Audio PT2's ability to deliver musical detail is clearly amazing. The tweeter's large membrane and radiating area provide higher power handling and a substantially lower cut off frequency. This membrane is thermally attached to a cast aluminum plate that facilitates cooling and dramatically increases dynamic range. The flared waveguide's wide horizontal dispersion projects an excellent off axis response. At the same time, vertical dispersion is limited, which reduces distracting floor and ceiling reflections. Perfect for line array applications. The recommended second order crossover cut-off frequency is 3 kHz or higher, although the crossover point can be lowered to 2,500 Hz if a 3rd order crossover is used.

Dayton Audio PT2C-8 Planar Tweeter is rated 4.6098 out of 5 by 41.
Rated 5 out of 5 by from You really can not go wrong with these.I used these to build a custom 3 way tower to play with. They sound great and are not fatiguing at high levels. I have them crossed at 4k and have no complaints. I have each tower being powered with a Dayton APA150. They are very clear and precise. As mentioned, they are vertically challenged so when one stands up you can clearly hear the top end drop off.I have each driver flush mounted in the baffle for a clean look. I have not decided how I want to finish the enclosure yet but I am leaning towards painting them.

Rated 4 out of 5 by from Short listening time, but jaw dropping sound.I built up a 500w boombox and placed this tweeter front and center. I am very fickle when it comes to tweeters and tend toward tuning the highs down a bit so they don't become irritating and fatiguing. I was Very Very pleased to have this guy handling the highs! Incredibly smooth, very nice off axis response and great authoritative control over the highs.Cymbals, tambourines, hand claps, 'T's and 'S's all came through with great clarity and control. Current the speaker is in the hands of a professional sound twiddler, so i'll have a great feedback point shortly.

Rated 5 out of 5 by from Clean, Clear, and mighty attractive.Bought these with the hope to have crisp clean highs without the extreme harsh detail of a small round dome tweeter. These were the high's to a 3-way speaker tower I built, absolutely what I was looking for. The clarity, detail and depth is astonishing. I have them crossed over at 5000hz (12db/2nd order) plays a perfect match to the 4 inch reference mid-woofer.

Rated 4 out of 5 by from Sweet and SmoothI have these paired with 2 Celestion 5" full rangers and an Emminence Beta 15 in an simple open baffle arrangement and all I can say is wow. I have gone back and forth between 5k second order and 3500 3rd order and settled on the 3500. I was waiting for all the components to break in before I wrote a review. At first I thought they were a little forward, but that was actually the Celestions and an L-pad took care of that. These seem to blend perfectly with this set-up. The staging is very wide and the image produced is awesome such that you can pick out exactly where the instruments are on the stage. Vocals being rock solid center stage. I have to say that these Planar Tweets are very revealing, open and can you say dynamic.. I was playing some Coltrane at moderate levels and the wife came into the room thinking someone was actually in the room playing the saxophone. I think that's the best thing you can say about a speaker set-up is that it's true to the recording.I've since blown the dust off the record collection and have been rediscovering music.One last thing. Each open baffle arrangement can see over 350 watts continuous from my Parasound HCA-3500 and possibly 0ver 500 watts depending on the ohm load. I've turned up to what most would consider to be very loud for a couple hours at a time and haven't had any issues.Great Job PE. Another successful speaker at a solid price especially when compared to "name brand" products of similar sound quality.

Rated 2 out of 5 by from No no, Dayton.I'm going to assume that whoever has been reviewing this item so far can't have tested it properly... At all. The specs are totally off. It can't handle anything close to 80 watts before it gets smoked. I bought some to use in a line array config after asking a question or two even here on the site. Now, I've got two dead and Im thinking what to do with d rest... Its probably OK for Home theatre though.

Rated 5 out of 5 by from well builtI got these Dayton planners, Dayton 2" mid domes, Dayton 8" designer series speakers, and the100 watt Dayton 3-way crossover for my first DIY project . When I received the order ,I though wow!! These are some well built speakers . I build a .8 cu FT with a 2.5" port 1 " . Installed these speakers, an the x-over . Running them off a 80 watt rms x 5 pioneer VSX-822 the speakers were a little rough sounding at first , but after I reversed the polarity on the mid an added an l-pad on the mid to turn it down a little bit , these tweeters really sound awesome. very crisp but not harsh at all . really clear sounding and can be cranked up LOUD an still sound great. They sound best at ear level .This project with all the Dayton products work great together an sound awesome .So if you r planning a project ,you wont be disappointed with Dayton products, or the prices.

What is the recommended crosso er freq in a 4th order active system?

Would you happen to know the dispersion angles of this, horizontal & vertical ? Thanks

Asked by: Bill the Cat
I am sorry, Dayton does not provide any specification for dispersion angles. They do have the response at various angles off axis in the FRD file under manuals and resources. That can get you a more accurate idea of the horizontal performance.

Many people think these are the same ribbons used in the Sunfire and Carver products.  Why is the recommended min crossover 2.5K to 3K but Sunfire and Carver cross these over at 1.5K.  They also claim very high power handling.

Hi. I would like to know if Dayton or Parts Express sells repair kits for these tweeters. I am in the process of repairing a friend's line array system and realized that all 8 of the PT2C- 8 were not playing and need to be repaired.

Asked by: TriniShawn
Unfortunately we do not offer repair kits for these tweeters.

Sorry my question was not very clear. If I use 2 tweeters flat on my car dash as a center channel, should the longest portion of the speakers be aligned in an east/ west configuration or north/ south?

Asked by: Bigkan
I would say North/South. I have a set of these in a 3 way configuration in my room and dayton isn't kidding around when they say that the vertical dispersion is very narrow!! So if you mounted them east/west, you would get a very narrow listening range left to right and you would have to mount them directly in front of the driver and passenger. I would guess the imaging would be better with them mounted north/south as well.
